An appropriate choice of different lighting fixtures, light bulbs, and lighting techniques can allow the mood, or atmosphere, created in any given space – whether is be a living space, a home office, a kitchen or bathroom, for example – to be adjusted to its purpose.

Lighting, of course, has a definite, practical purpose. It allows use to see each other, move about, and perform everyday tasks, safely, when natural light is unavailable, or insufficient. Above and beyond that basic practicality, however, lighting can be used to create atmosphere, or mood, in a space, which directly influences the attitude and behaviour of inhabitants of that space.
